Reply to Weird VCI LED behavior

Hey folks,
i have a black VCI 100 with FW 1.4. I flashed it myself a few months ago and everything worked fine. I was really happy with it.

As I'm currently on a break from school I decided to take the VCI with me when I'm going home to my parents. Said and done. Packed it in my suitcase (which was full of clothes, so the VCI should've had a comfy train ride).
6hrs later I unpacked it, plugged it in and...horror!! When I press a button some random LED lights up, but rarely the one of the button pressed. Some don't light up at all. It's really erratic. For example, when I press the left cue button the left sync button lights up. Same goes for a lot of other buttons.
The controls still work fine though which is really weird. I could still play a set, without any meaningful LED feedback though

I tried everything, restarted my computer and the VCI, re-imported the mapping, used a different USB cable...etc. I even opened up the VCI to check for visible damage or loose cables...but didn't notice anything.

I thought of reflashing the fw, but I don't have the kit with me.

Does anyone have any good advice?

Thanks in advance!
